This invention relates to draft devices and more particularly to apreferably integral casting adapted for application at the ends of carunder-frames, so as to cooperate withl the coupler, center sills anddraft keys of a car.

The principal object of my invention, generally considered` is theprovision of an in? tegral draft device which is formed to function as acoupler striking and carrier iron with rearwardly extending earspreferably functioning as cheek plates for a railway vehicle or car,said member being preferably connected so as to embrace the ends ofcooperating center sills.

An object of my invention is the provision of a combined strikingcasting and coupler cariier iron with rearwardly extending portionsserving as Farlow or double slotted cheek plates connected with thecenter sills on the outer surfaces thereof.

Another object of my invention is the provision of a combined castingadapted for connection at the end'of a car so as to embrace the adjacentends ofthe center sills, the length .of said casting being such that itextends beyond the ends of said sills to increase the `effective lengththereof andmake it possible to utilize shorter sills.

A further object of my invention'is the.

provision of an improved construction for car under-frames andparticularly the end portions thereof wherein an integral member isprovided embracing the ends of the center sills thereof and holding thesame more rigidly in position. said member being provided withrearwardly extending portions connected with said center sills andslotted for the reception of draft keys, the edges of said slots beingflanged with .the ianges extend# ing into cooperating slots in thecenter sills f or more securely connecting said casting and center sillstogether, the slots in the center sills extending to the adjacent endsthereof for facilitating the application of the east- -ing thereto. saidcenter sill ends being also coped for the reception of a web connectingportions of said casting, the top of said Web, when the members areassembled, being substantially flush with. the tops of the center sills.i

A still further object of my invention is the ASSIGNOR T THE SYMINGTONCOIVI- improvement in underframe construction wherein an integralcasting is employed for connecting the ends of the center sills andacting as a combined striking casting and cheek plates, the cheekcasting being either of the Farlow. that is the doubleslotted, type, orsingle slotted, the adjacent ends of the center sills beingcorrespondingly slotted to the ends thereof so as to embrace flangesframing the cheek plate portion slots. i v

Referring to the drawings 'in detail, in

pla-te portions of said which like parts aredesignated by like referencecharacters, there are illustrated railway vehicle center sills 1 alsofunctioning as draft sills, a body bolster, or the bolster transoms, 3,

in a well known manner. Between the transversely extending portions ofthe body bolster 3 a center filler casting 4, which is also preferablyadapted to function as a draft rigging back stop, is employed. Thebolster top cover plate 5 preferably extends over the center sill coverplat-el 2 in the usual manner and the bottom bolster cover plate 6extends below said main bolster portions or transoms 3, a center plate 7being applied beneath the bottom cover plate 6 and the casting 4, in

accordance-wit-lrusual practice.

nected an integral draft device 8, said device being preferably formedas a casting with a coupler strikin'g portion 9, a carrier iron portion10, and rearwardly or inwardly extending ears or cheek plate portions11. Said cheek plate portions, in the embodiment illustrated in Figures1 to 5, inclusive, are shown doubly slotted or of the Farlow type, thatis, each portion is provided with an outer or forward slot 12 adaptedfor the reception of a front draft key 13 and an inner or rear slot 14Ifor the reception of a rear draft key 15. Said cheek plate portions 11are preferably connected to the outer sides of the webs 16 of the'center sills 1, the slots 12'and 14 therein being preferably framed byflanges or beading 17 therearound. Said beading or flangedi portions 17preferably extends both ways from the web 18 of the cheek plate portions11, the inwardly extending portions thereof being embraced incorrespondingly slotted portions 19 of the center sills, whereby thestrength of connection therebetween is much improved. The slots 19 inthe center sills preferably extend as continuous slots clear to theadjacent ends thereof whereby 45 the combined casting 8 may be assembledwith said center sills after the same have been connected together andto the other associated parts of the car underframe. That is, the draftmember 8 may be slid into place 50 from the corresponding end of the carwith the flanged portions 17 moving in the slots 19 of the center sillsto the rear or inner ends of said slots.

The web 18 of the cheek plate portions 11 is 55 preferably continued fora material distance beyond the inner or rear portions of the flange 17,as indicated at 20, so as to provide for the more rigid connection withthe center sill webs and for improving the strength of said 60 cheekplate portions adjacent the ends of the slots 14 therein. The webportions 20 and adjacent flanged portions 17 may, if desired, be bracedtogether by triangular web portions 21.

As illustrated particularly in Figure 1, the

connected to a cover plate 2 andv cheek plate portions 11 are preferablyconnected to the webs 16 of the center sills by rows of rivets above andbelow the slots 12 and 14, the forward portion of the Idraft member overthe front slots, however, being preferably increased in depth, therebyal-. lowing for another row of rivets 22, said increased portions beingpreferably also connected by a horizontal shelf or web portion 23extending between the cheek plate portions 11 for improving -thestrength of the casting. Y The upper surface of said web 23, whenconnected with the center sills 1, is preferably flush with the uppersurface of the upper flanges 24 thereof so that said center sills, and

f particularly the u per flan e ortions 24 At the end of the centersills 1 there is conp g P thereof, are coped, notched or cut away, asindicated at 25, for the reception of said flange or shelf portion 23.The cover plate 2 preferably extends between the upper flanges of thecenter sills 1 and the web portion 23, thereby serving to furtherlstrengthen the connection therebetween, .common rivets being preferablyprovided between the web 23, cover plate 2 and end sill 26, asillustrated particularly in Figure 1. y

Beyond the end of the cover plate 2 the web or shelf portion 23 of thedraft casting 8 is preferably offset upwardly to form the upper flangeor web portion 27 of the coupler striking portion 9. c From aconsideration of Figure 1 particularly, it will be seen that saidcoupler striking portion 9 comprises, in addition to the portion 27, theupright webpor-- 100 tion 28 and lower flange portion 29 forming aU-shaped section which may be strengthcned by longitudinally extendingwebs 30, the rear portions of which preferably taper or decrease indepth until they merge with 105 the web 23 at the inner edge thereof.

The coupler carrier portion 10 is preferably U-shaped in section alsowith a horizontal web portion 31, depending flange portions 32 andlongitudinal connecting we portions 33. A wear plate, illustrated inFigure 1, may be applied over this member in accordance with the usualpractice. The ends of the portions 9v and 10 of the combined casting 8connect directly with the forward 115 ends of the cheek plate portions11, said ends being preferably provided with flanges 34 framing thecoupler stem opening. Said flanges 34 preferably extend both inwardlyand outwardly from the web 18 of the cheek plate portions 11 and bracingwebs 35 arid 36 preferably exte'nd therefrom to the adjacent flangeportions 17. v

The lower flan ges 37 of the center sills may be cut away adjacent theouter ends, as indicated at 38. The inwardly extending portions of theflanges 17 may be decreased in depth along the horizontally extendingportions between the ends of the slots 12 and 14 as it is not necessarythat said flanges be as 130 strong in such positions as adjacent theends*- of said slots. vThe draft keys 13 and 15 serve to support theinner end of the coupler stem 39 and the front follower 40, resectively, and operatively connect said members with, as well as support,the front portions of a yoke 41. The yoke 41, in the present instance,is shownas of the horizontal type, the forward arms of which are slottedfor the reception of said draft keys 13 and 15 and the rear or U- shapedportion of which preferably abuts against the back stop member 4 andembraces the rear follower 42.

Between the front follower and rear follower 42, a cushioning mechanism,illustrated diagrammatically by dot and dash lines, may be employed. Forsupporting the rear or inner end of the yoke 41, angular bracket members43, preferably riveted tol the webs 16 ofthe draft sills by counter-sunkrivets 44, are employed. For supporting the cushioning mechanism, usualforms `of carrier irons 45, connected' to the 37 of the center sills inmay be utilized.

In the embodiment of my invention illustrated in Figures 6 and 7, asimilar construction of combined casting 8a is utilized with theexception that the cheek plate portions lla are merely formed with anydesired manner,

in each portion so that the draft sill slot 19a Blf the reception of thesecond or rear for receiving the slot flanges 17 a need not be continuedfrom the ends of the center sill webs 16a for as great a distance.Separate cheek plates 46 may then be employed for draft key 15a. In thisinstance the web 47 of said second check plate is shown continued to amaterially greater distance to the rear of the slot 14a therein forproviding-the necessary riveting area, and separate slots 48 in thecenter sill web 16a for the reception of the flanges 49 may beconsiderably longer than necessary for said flanges" so that a flangedreinforcement 50 in said slot 48 to the rear of the rear portion of saidflanges 49, may be employed.

In the embodiment illustrated in Figures 8, 9 and 10, a casting 8b isemployed which may besimilar to the casting 8 or 8a previously describedwith the following exceptions. In the previous modifications describedit was necessary to cope or. out away the end portions of the upperflanges 24. of the center sills 1, and no direct connection was providednecessitate cutting away the top flanges thereof. This constructionprovides a slot 51 in the cast-ing 8b 'for receiving each center sill,at the saine time, the slots 19b in the webs of the center sills receivethe flanges 17b of the cheek plate portions l1b of said casting. In

lower flanges.

a single slot 12a ,l

'ingly slotted portions insaid sills,

this'modification, there is no direct connection between the innerportion of the web or shelf 23b and the adjacent upper edges of thecheek plate portions, said upper edges being preferably reinforced bytriangular or tapering web or gusset portions 52 extending rearwardlyfrom the forward flanges .34b of the casting 8b.

The connection between the lower portions of the casting and the lowerflanges 37 of the center sills 1 is further strengthened in the presentembodiment, by or web portions 53 overlying the lower flanges 37 of thecenter sills 1 and connected thereto by rivets 54. These web portions 53are preferably braced to the casting 8b by triangular gussets 55.therefore, the upper portion of the casting' Sbvis slotted to avoidweakening of the ends of the sills, whereas the connection between thelower portion thereof and said sills is strengthened by the rivets 54extending through the web sill flanges 37.

It will be apparent that by virtue of my aforedescribed construction, acombined Astriking casting and carrier iron with integral v rigidifiesand reinforces the underframe construction at such places.
